This review is for those players who have an older edge from the 90's like myself. The trem bar won't slide in the bridge hole in stock form. I had to use a 5/32 drill bit (by hand) and shave off some of the inner portion of both bushing. I rotate the drill bit by hand while pushing it in and out slowly shaving the inner portion of the bushing. I count as well, so as to shave an equal amount on both bushing. Hope this helps any ot those players that found it wouldn't go in the bridge without a lot of force.
